PISTON-DRIVING ROD ARRANGEMENT FOR RECIPROCATING COMPRESSOR
摘要
<p>The arrangement is applied to a reciprocating compressor comprising: a reciprocating piston (10); and a driving rod (9, 40) having one end (9c, 41) coupled to a driving means (DM) and an opposite end (9b, 42) cooperating with a joint pin (50) mounted to the piston (10), and carrying one coupling longitudinal extension (43) fitted in the joint pin (50) and there retained so that the driving rod (40) displaces the piston (10) in its suction stroke. The joint pin (50) is coupled to the piston (10) during the compression stroke along a longitudinal extension of the side surface of the joint pin (50) larger than the difference between the total longitudinal extension of the latter and the height of the opposite end (42) of the driving rod (40).</p>
